MEANS IOR ORNAMRNTING IREPARED .ROOFINGL` To all whom z'tmag/ concern.'Be `it knownthat I, WILLIAM DnN LANY, a citizen of the United States7residing at Chicago, in the county of Cook'and State of Illinois, haveinvented certain new and useful Improvements in Means for'OrnamentingPrepared Roong, of which the following is a specification. f

This invention relates to the art ofymaking preparedv roofing which`consists of a flexible sheet or strip offelt or other fibrous materialimpregnated with molten asphalt orthelike and coated onone side with'alayer offgranularl material jor grit, such asv crushed stone,*'sl'ate,gravel or other like sub- The appearance ofsuchrooiing may be greatlyenhanced by creating a design upon the grit coating. According to thepresentv invention such a design iscreated by means of a rotary heatedcylinder having upon its periphery bars arranged in suitable config--uration, the sheet of grit-coated roofingvbeing fed by suitable meansclose to the pe-` riphery of this cylinder and at the same speed `as thesurface speed of the rotating cylindenthe heat from the said barson they cylindercausingjthe asphalt ycoating of the sheet to. liquefy alongdefinite lines and" be drawn up through the grit so as to appear on thesurface of the latter in the form of a t design corresponding to theconliguration ofv YSaid bars. The general object of the invention is toproduce a cylinder of improved construction for the purpose described. v

A special object is to provide a jstructure in which the design bars aremounted on the body of the Cylinder in" such a manner-that the set ofbars maybe maintained in true n' body becomes Warped by the extremeIheat, so that the proper coperative relation be` tween the bars and thesheet of rooiing being fedv thereto may be insured, and uni-y formityinthe appearance of the lines of the design on the roofing attained.

The rings vare fed by a valved pipe 19 v p p n 322, and `1oo y theseplates are provided with openings 23` permit escaped@` vthe materialpreferred being copper. These bars are at all times in goodheat-conducting relation to the cylinder, and may bearranged in anyconguration desired, according-'to the design to be applied to theroofing. In'the present instance I have shown, by way of example, anarrangement of the bars calculated to give an imitation of shingles uponthe roofing. This may be done by providing continuous circumferentialbars 24 to make relatively broad stripes ruiming parallel to the stripof rooing, and irregularly spaced short bars 25 extending parallel totheaxis of the cylinder between the adjacent circumferential bars, theshort bars being preferably narrower than the circumferential bars. Thecircumferential bars may `have notches Q6 therein alined with the shortbars 25. The

short bars 25' at one end of the cylinder may be cut -down as at 25a sothat their active faces terminate short of the end of the cylinder, thisbeing for the purpose of leaving a plainI portion along one edge ofthe-strip of `roof-lpg, which portion is overlappedA by the edge-of thenext strip when laid on the roof.

The strips of roofing are laid on the roof horizontally and the broadlongitudinal stripesv thereon made by the circumferential bars 24'imitatel the shadow thrown by the lower edge yofa row of shingles on ashingle roof, while the narrower stripes made by the bars 25 and thenotches 26 imitate the spaces between the side edges of adjacentshingles.

:Inorder t0 minimize radiation from the cylinder in the spaces' betweenlthe bars, I preferably apply to said spaces a coating of heat-insulatingmaterial 27, such as asbestos cement in suitablethickness.

It sometimes happens that the body of the cylinder will warp on. accountof the extreme and continuous heat applied to its interior,

and this warping, if means were not providedto offset it, would `causeirregularity in .they application of the design to the roofing.

I have taken care of this difficulty by mounting. the vbars 24 and 25 insuch a manner that ytheyfmay be adjusted with respect to the peripheryof the cylinder body so as to maintain' true cylindrical contour of thenetwork of bars as a'whole, irrespective of the warping of the' cylinderbody. `In the present instance the bars'are 'secured to the cylinderby'cap screws 28l which are inserted from 'thefinterior of the cylinder.and pass outwardly loosely through holes therein, the tips ofthe-screwsbeing threaded into the bars. vAdjustment of the bars with respect. tothe cylinder surfacemay be effected by i placing shims' 29-atfsuitablepoints between the bars and the cylinder surface, the shims being* heldi-n place by tightening the screws 28.

thosesliilledintheart,'1and I therefore do' figuration according toadesign to be applied to the roofing, means for heating the bars, andheat-insulating material in the spaces between saidl bars.

Means for applying a design to pre-k pared rooling comprising, incombination, a hollow cylinder having means for rotatably supporting it,means for interiorly heating the cylinder, a plurality ofheat-conducting bars on the peri hery of the cylinder a1'- ranged in acon guration according tothe design to be applied to the roofing, thecylinder and said barsl being of good heat-conducting material, andheat-insulating material filling the spaces between said bars onV theperiphery of the cylinder.

Means for applying a design to pref pared roofing comprising, incombination, a cylinder having on its external periphery a series ofheat conducting bars arranged in a conguration according to a design toyse be applied to the roong, `the bars being in intimate heat-conductingrelation to the periphery of the cylinder, means for heating thecylinder and the bars, and means for minimizing radiation from theperiphery of -the cylinder except through said bars, the

latter. means consisting of heat-insulating cement applied'to'theperiphery of the cylinder in the spaces between said bars.
